That may help if someone used the same kit you have.

Sounds like you have a (Hot) wire going Directly to ground.

I would start with unplugging the rear harness (If it is in sections) and tracing where it is making a direct ground.

Also check for pinched wire/wires where they are run thru the cab and bed.
